I am not responsible if this fries any of your machines, deletes all your data, eats your breakfast etc. It worked for me so I decided to post it in the wiki for other people who want to try this and skip the googling. Feel free to edit this page, correct typos, add new cool ideas and so on. That's what a wiki is for, right?

How to get the multicast address and port - the quick and dirty way - with tcpdump

Play it using mplayer

For me it did not really work, mplayer always played it back at 48000hz - although I specified it otherwise - and thus pitch was too high and lots of buffer-underruns (guess why ; ) Mplayer ignores in that case your rate parameter and uses the rate from formatstring(dvdpcm). This works for me good

You can stream your audio to a lot of PCs (in different rooms) and playback songs synchronic (You just need to fist start the clients for the vlc playback and then the transcoder) This way I wrote a little shell script to start playing music in my whole house ;-)
